      Server Description

      An ultra-high memory virtual machine featuring dedicated high-frequency Intel cores for memory-bound workloads requiring minimal parallel compute.

      Memory Optimized

      Microsoft Azure FX16-4ms_v2 is a memory-optimized virtual machine from the FXmsv2 family, featuring 4 dedicated vCPUs on 2 physical Intel Xeon 8573C cores running at 4.2 GHz. It is configured with 336.0 GB of RAM, providing an extremely high memory-to-core ratio of 84.0 GB per core. The instance lacks local storage and GPUs but is premium storage capable. Performance benchmarks highlight top-tier single-core capabilities, with a Geekbench single-core score of 2278.0 and strong single-threaded compression speeds. Conversely, multi-core performance is weak due to the low core count. This server is highly specialized for memory-intensive workloads that do not require heavy parallel compute, such as in-memory databases, caching layers, and text processing.

      Workload Profiles

      0.53Score
      Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
